Gamete, gestational carrier, gestational surrogacy, Gestational Surrogacy Act, GnRH agonist
Gamete
An egg or a sperm.
Gestational carrier
A woman who carries an embryo created from other people's egg and sperm, with no genetic link to the child. PLS surrogates are 21 to 43 with at least one healthy full-term pregnancy; see requirements.
Gestational surrogacy
Surrogacy with a gestational carrier. Every PLS journey is gestational; see what is gestational surrogacy.
Gestational Surrogacy Act
The 2005 Illinois statute that makes compensated gestational surrogacy agreements enforceable and provides for pre-birth parentage (reviewed by counsel). See Illinois surrogacy law.
GnRH agonist
A class of drugs, including Lupron, that switches off the brain's signal to the ovaries when given daily.
hCG, HMBANA milk bank, ICSI, identity-release donor, implantation
hCG
Human chorionic gonadotropin, the pregnancy hormone an implanted embryo makes, measured by the beta hCG test.
HMBANA milk bank
A nonprofit milk bank accredited by the Human Milk Banking Association of North America, which screens donors and pasteurizes milk. See lactation and milk donation.
ICSI
Intracytoplasmic sperm injection: injecting a single sperm into an egg in the lab.
Identity-release donor
A donor who agrees her identity can be given to the child at adulthood. See donor types.
Implantation
The embryo attaching to the uterine lining, in the days after transfer.
Independent counsel, intended parents, IVF
Independent counsel
A separate attorney for each side of a surrogacy agreement. PLS refers to independent attorneys rather than employing them. Illinois now requires independent counsel for both intended parents and surrogate (reviewed by counsel).
Intended parents
The person or couple who will raise the child and become its legal parents.
IVF
In vitro fertilization: eggs are fertilized in the lab and the embryos grown before transfer. See IVF for surrogacy.
Known donor, lining check, lost wages, Lupron
Known donor
An egg or sperm donor the recipients already know, also called a directed donor.
Lining check
The ultrasound near the end of the estrogen phase that measures the uterine lining and sets the transfer date. See the FET protocol.
Lost wages
Income a surrogate, and in PLS agreements her partner, loses for appointments, transfer, bed rest and delivery, reimbursed from escrow with documentation. See lost wages.
Lupron
Leuprolide, used to suppress a surrogate's ovulation before transfer or to trigger egg maturity in a donor. See Lupron.
